日本JIS不銹鋼材料標準的牌號表示方法為SUS＋數字編號。其中，S：鋼；U：用途；S：不銹；數字編號基本采用美國AISI的牌號表示方法。

 根據AISI的牌(pai)號表示(shi)方法，即：2-Cr-Ni-Mn系；3-Cr-Ni系；4-Cr系（6-沉淀硬化系）。

 日本(ben)獨特(te)的(de)牌(pai)號(hao)，采用類似(si)的(de)AISI牌(pai)號(hao)在(zai)其(qi)后加J1、J2來表(biao)示(shi)。舉例：SUS201、SUS304、SUS304J1。

 按照鋼(gang)(gang)(gang)(gang)材的形(xing)狀、用(yong)(yong)(yong)(yong)途和制造方法等，當需要用(yong)(yong)(yong)(yong)代(dai)號(hao)表示時(shi)，在牌號(hao)后(hou)面加上相應號(hao)，如下所示：B：棒(bang)材；CB：冷(leng)加工棒(bang)材；HP：熱(re)軋(ya)(ya)鋼(gang)(gang)(gang)(gang)板；CP：冷(leng)軋(ya)(ya)鋼(gang)(gang)(gang)(gang)板；HS：熱(re)軋(ya)(ya)鋼(gang)(gang)(gang)(gang)帶(dai)；CS：冷(leng)軋(ya)(ya)鋼(gang)(gang)(gang)(gang)帶(dai)；CSP：彈簧用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)帶(dai)；WR：線材；Y：焊接(jie)用(yong)(yong)(yong)(yong)線材；W：鋼(gang)(gang)(gang)(gang)絲(si)；WP：彈簧用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)絲(si)；WS：冷(leng)鐓用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)絲(si)；HA：熱(re)軋(ya)(ya)角(jiao)鋼(gang)(gang)(gang)(gang)；CA：冷(leng)軋(ya)(ya)角(jiao)鋼(gang)(gang)(gang)(gang)；TB：鍋爐及熱(re)交換器用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)(guan)；TPY：配(pei)(pei)管(guan)(guan)(guan)(guan)用(yong)(yong)(yong)(yong)電焊大口(kou)徑鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)(guan)；TP：配(pei)(pei)管(guan)(guan)(guan)(guan)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)(guan)；TPD：一般配(pei)(pei)管(guan)(guan)(guan)(guan)用(yong)(yong)(yong)(yong)鋼(gang)(gang)(gang)(gang)管(guan)(guan)(guan)(guan)。舉例：SUS304-B、SUS304-WR、SUS304-HP。
